It is a Light Detection Photosensitive Sensor Module, Working Power Supply: DC 3.3V~5V, It has small size, high efficiency, long term stable and reliable quality,easy installation and use, Applications:Suitable for Smart Car/brightness detection etc

1.
photodiode module most sensitive to environmental light intensity ,
generally used to detect the ambient brightness and light intensity ,
can be common with photosensitive resistance sensor module in most cases
, the difference between the two is that a better directional
photodiode module , you can sensing light in a fixed direction .

2.
module dull conditions or when the light intensity of less than the set
threshold , DO port output high when the ambient light intensity
exceeds a set threshold, the module output low in D0 ;

3.
digital outputs D0 can be directly connected with the microcontroller
through the microcontroller to detect high and low , thereby detecting
the light intensity changes in the environment ;

4. digital outputs can directly drive DO OUR relay module , which can be composed of a photoelectric switch ;

5. AO
analog output modules can be connected and shop AD through the AD
converter , you can get a more accurate light intensity values ;
